Recycle your old puzzles.
I did not create this craft, I submitted the idea to familycrafts.about.com for the Monday challenge of what to do with stray puzzle pieces as it was a craft my son did when he was in early grade school and it was selected to be featured.
(Pic is not mine, it is of Sherri Osbourn's creation at the following website as she created the idead that I submitted)
Glue the sticks together at the edges to make a frame.
Glue the puzzle pieces around the craft stick frame.
Trim the photo to the same size as the frame and then glue it to the back side of the frame.
Finally, glue the pop tab to the back to use as a hanger.
